GPC3-targeted CAR-T Cell for Treating GPC3 Positive Advanced HCC

Overview

Patients with hepatocellular carcinoma (a type of primary liver cancers) are enrolls in this study. The cancer has progressed after standard treatment, or the patient cannot receive regular treatment.

Investigator made a gene called chimeric antigen receptor derived from an antibody that recognizes Glypican 3, a protein detected in in a large proportion of hepatocellular carcinoma. The gene will introduce into T cell from patient's blood to make them recognize and kill cancer cells.

The aim of this study is to evaluate the efficacy, tolerance and safety of chimeric antigen receptor-modified T (CAR-T) cell targeting Glypican 3 for advanced hepatocellular carcinoma.

Full Title of Study: “Clinical Study of GPC3-targeted Chimeric Antigen Receptor T Cells fo Treating Advanced Hepatocellular Carcinoma”

Study Type

  • Study Type: Interventional
  • Study Design
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: October 1, 2021

Interventions

  • Biological: CAR-T cell immunotherapy
    • Patients enrolled will recieve three different doses of the CAR-T cell every two weeks as follows: Dose 1: 1×10^7/m2 Dose 2: 3×10^7/m2 Dose 3: 1×10^8/m2 The cell numbers are calculated according to CAR-positive T cells.

Arms, Groups and Cohorts

  • Experimental: CAR-T cells
    • CAR-T cells targeting GPC3 will be administered to enrolled patients with hepatocellular carcinoma.

Clinical Trial Outcome Measures

Primary Measures

  • The safety of CAR-T immunotherapy
    • Time Frame: 2 months
    • After each dose of T cell infusion, the adverse effects related to T cell therapy such as fever and jaundice are observed.

Secondary Measures

  • The therapeutic effect of CAR- T immunotherapy
    • Time Frame: 3 months
    • Radiological evaluation of the tumor size after infusion of CAR-T cells.
  • Peripheral tumor markers
    • Time Frame: 3 months
    • After CAR-T cell infusion, the HCC markers including AFP are tested regularly in blood.
  • Peripheral CAR-T cell testing
    • Time Frame: 3 months
    • The number and proliferation in vivo are tested with Flow Cytometry regularly.
